The speeches are giving Clinton added visibility as she contemplates a run for the White House in 2016. Since leaving office in February, she has spoken to such groups as the American Society of Travel Agents and the National Association of Realtors.

She also greets well-wishers and takes pictures afterward, but travel is negotiated as a part of her fee. That could include a private jet, the Times reports.

The fee appears to be comparable to what former President Clinton receives for speeches delivered in this country, though he has earned more for some speeches outside the United States.

For instance, he was paid $700,000 to speak to a company in Lagos, Nigeria, last year. The former president earned a total of $17 million from speeches last year, the Times reports.

Those legislators who may challenge Clinton for the presidency are barred from taking honorariums for such events — and past presidential candidates, including former Arkansas Gov. Mike Huckabee, have been scrutinized for the practice, the Times reports.
